How this service works
Full profile of one coin by id: name/symbol, description, categories, contract addresses per platform, links (homepage, explorers, repos, social), hashing algorithm, genesis date, and a market snapshot in your currency: price, rank, market cap, fully diluted valuation, 24h volume, ATH/ATL with dates and distance, circulating/total/max supply, 24h/7d/30d/1y change. One call for the metadata a token-risk or research agent otherwise assembles from five. Cached in-process for 5 minutes.
Output
Returns a JSON object with the coin's name, symbol, CoinGecko rank, current price and market stats (ATH, ATL, 24h high/low, market cap, volume, supply figures, price change percentages over 24h/7d/30d/1y), sentiment percentage, watchlist user count, categories, description, genesis date, hashing algorithm, social and explorer links, and contract platform details. Data is sourced from CoinGecko and timestamped.
Example use cases
Research crypto before investing
“Give me a complete profile on Solana — current price in USD, market cap, ATH, how it's changed over the past 30 days, and a quick description of what it is.”
Monitor token fundamentals for a portfolio
“Fetch the coin profile for usd-coin so I can check its circulating supply, fully diluted valuation, and which blockchain platforms it's deployed on.”
Summarize a coin for a newsletter
“I'm writing about Cardano — can you pull its CoinGecko profile including the description, categories, genesis date, Reddit link, and current sentiment score?”
Technical details
Endpoint
GEThttps://agent402.tools/api/coin-profileWhen to prefer
Use this endpoint when you need a rich, all-in-one profile for a single cryptocurrency — combining real-time market data, metadata, social links, sentiment, and categorization in one call. Prefer this over a simple price ticker when you need context like ATH, supply, description, or categories. Best when the coin ID is already known; use coin-search first if you only have a ticker symbol.
Side effects
- Unknown coin ID returns an error — use the coin-search endpoint first to resolve a ticker symbol to a valid ID
- Invalid currency code may return an error or default to USD
- Rate limiting or upstream CoinGecko unavailability may cause failures
- Cached vs. live data flag indicates freshness; stale data possible during high load
